http request interceptor - restful web service using cxf

Question

Trying to add headers to every request that my restful service receives. The below inbound http interceptor gets invoked, but does not add the header.

    package com.client.interceptors;

    import java.util.Collections;
    import java.util.List;
    import java.util.Map;

    import org.apache.cxf.interceptor.Fault;
    import org.apache.cxf.message.Message;
    import org.apache.cxf.phase.AbstractPhaseInterceptor;
    import org.apache.cxf.phase.Phase;

    public class ClientInterceptor extends AbstractPhaseInterceptor<Message> {
        public ClientInterceptor() {
            super(Phase.PRE_INVOKE); // Put this interceptor in this phase
            System.out.println("inside constructor");
        }

        public void handleMessage(Message msg) throws Fault {
            // process the message

            System.out.println("inside interceptor");
            Map<String, List> headers = (Map<String, List>) msg
            .get(Message.PROTOCOL_HEADERS);

            headers.put("token",
            Collections.singletonList("abcd1234xyz56sa"));

            msg.put(Message.PROTOCOL_HEADERS, headers);

        }
    }

How can this be achieved?

Well ya i have one solution for the same. look this. it might help.

Client client = Client.create();
     WebResource webResource =client.resource("URL");

     MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
     queryParams.add("json", js); //set parametes for request

     appKey = "Addkey " + appKey; // appKey is unique number

     //Get response from RESTful Server get(ClientResponse.class);
     ClientResponse response = null;
     response = webResource.queryParams(queryParams)
                            .header("Content-Type", "application/json;charset=UTF-8")
                            .header("Authorization", appKey)
                            .get(ClientResponse.class);

     String jsonStr = response.getEntity(String.class);
